sonerie unnmpwm closures for bottle-s and j-.ire of the typeillustreted in U. SfPatent No. 934,832 granted i o 1 i o to C. (l. .i erker Septemoer l, 1903. ouch closures are commonly termed bottle espe and ere prinolpsrlly used for sealing bottles. in the manu-facture and use oi' es ps such es shown in said patent, it lies been found that the lifting tulo is iieble to teer oli when extracting the cup from the bottle unless the csp is mede of tough end rather expensive material. This is due to the feet that in the oep shown in seid patent the stspie protects the middle portion of the tongue only leaving the side edges Jfree to tear at the ends o' the iii-shaped cut which outlines the tab. It is further due to lthe fact that when the tali is pulled the. under leyeroi the csp takes ail of the strain on the staple, the upper layer constituting the tab. For the above reasons it has been found that the tabs frequently tesi' ofi" due to the weaknesses` described endto carelessness in puliing the tub more :it one sido than the other.

The present improvement consists in securing the tal) by vtwo stepleserranged to bridge the ends of the isi-shaped out. This results in preventing the tub from tearing at the ends ot' the out, and it results in a stronger construction as one end ot each staple i anchored in the cup outside of the tali so that the strain tendingl to Idislodge the staple is resisted by the full thickness of the Cap instead of y only one-half of the thickness, as in the Parker patent. The Inexiniuni strength oi' the tel) may therefore be utilized to dislodgerthe rap. rlie inven* tion iilustrsted'in the accompanying: drew ings in which:

Specification of Watters Patented JI 3.

Referring to the drawings l0 indicates the csp or ciosure which is usueiiy a disk and preferably-made from s single thickness of paper hoard or puip hoard. The teh llrnsfr be 'formed by cutting partiaily through the body of the oep along the outline of the teb end slightly along the teh, es described in the lia-erker patent. in the manufacture of the oeps the tale is siit from the body of the esp end seein pressed into 'the recess, as in Higgures Lto, so the oeps een he compactly assembled in tubes for shipping purposes. To facilitate raising the isbv when extractingthe csp from the bottle e. slight recess 12 1s pressed in the csp adjacent the tree end of the teh in 'tno eourse oep outside oi the telo so that the iii-lhy strength vof 'the csp resists the disiodging` of these outer ends the staples. The inner ends of the staples ere close toffether so that the two reinforcement along the hinge edge oi the teh. f i

As shown in Figure 2 short staples 13 ere used to .liridge the ends of the Usheped out at the hinge of the tel). These short staples may lie used when the cap is mede of good quality of peper boord but by the use of the longer staples shown in Figure i., or ofthe arrangement shown in Figure 3, e. somewhat cheaper boord will give satisfactory results.

As shown in Figure 3, the short staples 13'a are supplemented by s third staple. 14 mranged alongv` the hinge of the tab et its middie portion and in iine with the. staples 13st it Wiii be apparent that in each of the `forms of my invention the hinge of thetab is strengthened and the telo is prevented from tearingJ et the ends ci the ii-shaped cut eren though it oe pulied 'more on one side than the other. it will also he apparent that the staples 13 and i3 ere more securely anchored thun the staples in the latent referred to, innsn'iuch ns the outer end of each staple is secured in the body o esp snai."

staples "rorni neer y continuous hy Letters Patent is:

L A. bottle oep having a lift-ing tab which is formed hy horizontal splitting and raising eine portion of the rap in combination with "staples in iine with the hinge of the tab Aandarranged across itsrnergin to prevent tenring at the hinge. I

2., A bottle oep having :i lifting tab which is foi-ined by horizontal splitting nd raising of e portion of the cap in combination with two staples arranged along the hinge edge of the teh the inner ends ot the staples passing through the. hinge of the tab and the i outer ends ofthe staples passing through the body of the :'ap outslde of t e tab.

3. A hottie -ap having a lifting tab which is toi-med hy horizontal splitting and raising of e portion ot' the rap in combination with two staples arranged along,r the hinge edge of the tal) the inner ends ot' the staples passingr through the hinge ot the tal) and the outer ends of the staples passingr through the body of the cap outside ot' the tab, the inner ends o' the staples being adjacentand the staples extending along;` the greater portion of the hinge ot' the tab.
